A practical guide to toner assortment strategy for distributors and wholesale buyers: category entry, line depth, and what to compare across leading lines.
Toners sit at a useful point between education and conversion. Buyers search them by routine need, but they also connect naturally to cleanser, serum, and moisturizer follow-up pages.
